semi-recently, I upgraded to a CK Worldwide 130 series flex-loc torch and LOVE IT!  It was much easier on my hands for welding thin walled tubing for car projects (SS and AL).Although this torch + Weldcraft #12 cup w/ large diameter lens is better than the huge wp25? Everlast torch I had before, the #12 cup (1 & 7/8" length ?) is still too tall (long) for this ck 135 series torch.  It forces me to tilt the torch away from the material at an awkward angle  just to fit the cup an appropriate distance from the metal..  So, that hand position of angling the torch away from the metal makes it challenging to hold steady.  With smaller cups, this problem is gone, but I don't get the good gas flow of the #12.  If I had a shorter #12 cup length, the torch would be more parallel to the tubing, thus easier to keep my hand steady, thus better looking welds .So, do you guys know of any GOOD new stubby #12 welding cups that work with large diameter gas lens and still provide good gas flow?  I ask because I've heard in the old stubby ("short length") cups didn't provide as uniform gas coverage compared the full length #12 cups.  I was hoping some new better designs exists, so do you guys know of any?Last edited by TheMeatHead; 07-23-2013 at 09:40 AM.

Reply:isn't that a small diameter gas lens?  I'm looking for a stubby nozzle that works well with the large diameter gas lenses because I like the wide even flow characteristics of the large diameter gas lens.

Reply:Originally Posted by shovelonI think there is no such beast. The one you have is the large one to the right?
Reply:the large diameter #10 cup isn't all that much shorter than the #12.  It just necks down an extra 1/8" or so in diameter.The problem isn't the ceramic/alumina cup, the problem is the large-diameter gas lens collet bodies.  They are just so damn long to begin with, as you said.  Never seen any stubby cups for the large diameter gas lens collet bodies. 1st on WeldingWeb to have a scrolling sig!

Reply:What do you guys think of this?:11/16 length is slightly shorter than my current #12 ~15/16 with Weldcraft stubby gas lens...

Reply:3/4-16 is for the medium gas lens, not the large gas lens, ain't it? 1st on WeldingWeb to have a scrolling sig! HTP Invertig 400HTP Invertig 221HTP ProPulse 300HTP ProPulse 200 x2HTP ProPulse 220MTSHTP Inverarc 200TLP HTP Microcut 875SC
Reply:Oscar,  you are correct sir!  So, as of now 2 options came to my mind:1. #10 or #11 cup with standard size gas lens (shorter length than large diameter gas lens cups).  (How will this affect performance welding stainless steel exhaust compared to the large diameter #12 w/ large gas lens?)2. Machining the Teflon spacer to half or to 1/3 it's original thickness.  (Is this even possible and would it create any other problems?)

Reply:Tec Torch makes a stubby gas lense/insulator/collet/cup for your torch. I have it on my WP17.Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li  ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea.
Reply:You could put a couple of TIG fingers or a folder up glove under your wrist to prop it up. Or turn the head on the flex loc about 90 degrees from where you have it to move the head away from the work piece. Or try a small gas lens with a #8 cup and see if it gives you enough coverage.
